Phoenix Mini-Guardian HEPA System

TS-261B

The Phoenix Mini-Guardian HEPA System is the compact, variable air speed version of our popular Phoenix Guardian HEPA System.

Maximum delivered air flow with 3-stage filtering in place is over 4�5 CFM and will clean one air change of a �4 x �4 foot room in less than four minutes while drawing less than two amps of power. This makes the Mini-Guardian HEPA System perfect for smaller remediation projects where space is at a premium and reduced air flow essential. A template on the intake grill makes it possible to take air-flow measurements with the Phoenix Kestrel 3000 Multi-Meter.

The Mini-Guardian HEPA System’s 3-stage filter design with true HEPA filtration will remove virtually all hazardous particles from the air and an optional fourth stage filter of activated carbon and potassium permanganate will absorb a wide range of odors and gases. The unique 24” canister HEPA, manufactured for the Phoenix Mini-Guardian HEPA System, contains nearly 200 square feet of surface area. This allows maximum air-flow and significantly extends filter life.

�. Remove the handle assembly (consists of two handle brackets and handle tube), two metric socket head cap screws M�0 x 35mm length, and 8mm hex key from the packed parts supplied with the unit.

Figure 1: Handle assembly

alexandrahHighlight


2. Locate the two mounting holes for the handle assembly on the Mini-Guardian HEPA System cabinet. They are located in close proximity to the top of the cabinet near the corners. A lock nut should be visible through each of the mounting holes and is held in place by a retainer plate secured to the cabinet shell. Verify lock nut is visible in each mounting hole.

3. Place a socket head cap screw (M�0 x 35mm) into each of the holes in the handle end brackets. Position the handle assembly up against the Phoenix Mini-Guardian HEPA System cabinet so as to align the cap screws with the mounting holes in the cabinet.

It may be necessary to tilt the handle assembly up at a slight angle in order to align the screws with the lock nuts. Use the 8mm hex key to press the cap screws into the mounting holes and engage the threads of the lock nuts.

4. Tighten each of cap screws using the 8mm hex key until the handle assembly is secured against the cabinet surface and all space between parts is eliminated.

2.2 Transporting the PhoenixThe Phoenix Mini-Guardian HEPA System should be upright when transported by vehicle. It may be tipped on to its back for loading and moving by hand or for use on location.

2.3 Location

Note the following precautions when locating the Phoenix Mini-Guardian HEPA System:

· It is designed to be used INDOORS ONLY.

· If used in a wet area, plug it into a GROUND FAULT

INTERRUPTER.

· DO NOT use the Phoenix Mini-Guardian HEPA System as a bench or table.

· The air inlet on top & the side outlets should be at least � foot from walls and other obstructions to airflow.

2.4 Electrical RequirementsThe Phoenix Mini-Guardian HEPA System can be plugged into a grounded �5 Amp circuit. It draws about 2 Amps with clean filters and no ducting. The amp draw will decrease slightly with added ducting and as the filters load with particulate.

If an extension cord is required, it must have a minimum of �8 gauge conductors if 25 feet long or less and �6 gauge conductors if greater than 25 feet long.

2.5 Air Ducting2.5A Inlet Ducting

Occasionally the area to be filtered is difficult to access and/or the unit cannot be located in the area. In such cases, the air can be ducted to the unit’s inlet.

A round �2” diameter flexible duct can be attached to the unit inlet on top. It connects by placing the wire in the duct under the four tabs on the top. It may be removed after use for easier transport and storage. Flexible �2” duct is available from Therma-Stor LLC.

2.5B Outlet DuctingA detachable rectangular exhaust collar is supplied that will allow �0” round lay-flat plastic duct to be attached to the Phoenix Mini-Guardian HEPA System outlet. Lay-flat plastic ducting is available from Therma-Stor LLC.

To attach ducting to a collar, remove the collar from the unit by sliding the collar upward out of the guide. Put the plastic duct end through the collar center. Roll the duct end outward so that it over-laps the outside of the collar. The duct will hook over the collar, preventing it from slipping off.

2.6 Negative Air DuctingThe Phoenix Mini-Guardian HEPA System can be used to filter and exhaust air from a space. By exhausting to outside the space, the space will be under a slight negative pressure. This will help prevent airborne particles from leaving the space, since the negative pressure will draw air in through openings in the space’s exterior.

The quantity of air exhausted depends on how the unit is ducted and what speed is used. A duct can be directed outside. Cover the other exhaust openings to direct all the filtered air outside. This would result in up to 400 CFM being exhausted on high speed and an equal amount of fresh air being drawn in.

CAUTION: Exhausting too much air from a space with open combustion devices (e.g. furnace, fireplace or water heater) can cause those devices to backdraft. This can contaminate the space with potentially fatal gases.

In such cases, the Phoenix Mini-Guardian HEPA System must be used in one of the following three ways:

A. As a filtering unit only. Exhausting no air from the space and thus causing no negative pressure or backdrafting.

B. Exhausting a very limited amount of air which does not cause backdrafting. In case B, the open combustion devices must be thoroughly checked to guarantee that they do not backdraft while the Phoenix Mini-Guardian HEPA System is running.

C. Direct the outlet duct from the Mini-Guardian HEPA System to the room with the open combustion device(s). This will positively pressurize the room, thus preventing backdrafting. As in case B, those combustion devices must be checked after the Mini-Guardian HEPA System is running to guarantee that they are not backdrafting.

The duct can be directed outside, exhausting a portion of the filtered air. The rest of the filtered air is recirculated inside the space. Blocking the other supply holes will determine the amount of air that is exhausted. By adjusting the blocking plates over the supply openings, the quantity exhausted can be adjusted down to no flow.

2.7 Power/Speed ControlThe power/speed switch is located in the recessed cavity on the unit front. When turned on to any speed, it powers the impeller fan and hour meter.

Occasionally the impeller fan may not start on low speed. If this occurs, rotate the speed control to high speed until the impeller fan starts, then adjust it to a lower speed.

Figure 6: Outlet ducting

CAUTION: Do not remove the top to access the filters with the unit on. Removing the top and filters while running can: (A) expose potentially fatal high voltage electrical parts, and (B) expose the dangerous rotating impeller fan.

2.8 Hour MeterA digital hour meter is located near the power/speed control on the unit front. It measures the cumulative time that the unit is turned on to tenths of an hour. It stores its total when the unit is unplugged. The previous total will be displayed when the unit is next turned on.

It resets to zero after 99,999.9 hours of operation.

3 Maintenance3.1 Air FiltersThe standard Phoenix Mini-Guardian HEPA System is equipped with three filters that progressively filter out smaller particles. An optional activated carbon/potassium permanganate filter can be used, giving a fourth stage of filter media (see Section 3.�A). These filters must be checked regularly. Operating the unit with dirty filters will reduce the airflow, but will do no harm to the unit. The unit can be run indefinitely with dirty filters.

The three standard filters used are listed below (as installed in the unit from top to bottom):

A. Polyester media pad pre-filter. Actual size �5-3/4” x �5-3/4” x �” thick. The white side faces up. This filter should be replaced when the airflow is reduced, it is visibly dirty or when it is contaminated by a previous job.

B. 25 to 30% efficient (per ASHRAE 52.�-�992), MERV-7, pleated fabric filter. Actual size is �5-3/4” x �5-3/4” x �-3/4”. This filter should be changed when airflow is reduced or it is contaminated by a previous job.

C. 99.97% DOP efficient HEPA filter. Actual size is �3-7/8” OD x 24” x 8-7/8” ID. This filter should be changed when airflow is reduced or it is contaminated by a previous job.

3.1A Activated Carbon/Potassium Permanganate FiltersOptional gas phase filters are available from Therma-Stor. They use a blend of activated carbon and potassium permanganate. This blend removes the vast majority of contaminants encountered in most filtering applications. The activated carbon removes the heavier volatile organics while the potassium permanganate removes lower molecular weight contaminants. This is well suited to the smoke odors present after fire damage.

The life of the media blend depends upon both the hours used and the contamination level. Another advantage of the blended media versus activated carbon only is

that part of the blend changes color as it loads up with contaminants. It starts out black, then turns pink, then brown, and finally white. It is best changed when it passes the brown stage and begins to turn white. It has lost most of its effectiveness at that point. When these filters are installed, the pad filter does not need to be installed above them. This allows the operator to check the media color through the top grill of the unit without removing the top.

The filter is the same size as the pleated fabric filter. Install it above the pleated fabric filter. The pleated fabric filter catches carbon dust that comes off the carbon filter before it reaches the HEPA filter.

The refillable carbon filter is metal-framed and can be refilled with carbon blend media purchased in 5-gallon buckets. The amount of carbon blend media loaded into the filter can be adjusted to the particular amount of gas/ odor removal required.

3.2 Checking AirflowThe airflow is checked using a Phoenix Kestrel 3000 airflow meter placed on the designated area on the top of the unit.

To check airflow:

· Remove any inlet ducting, but leave the top and all filters in place.

· Turn the unit on high. The airflow meter will indicate an air speed. Please set the air meter to read FPM (refer to the meter instructions to set the mode). To determine CFM see the chart below:

Figure 7: Checking airflow

Kestrel 3000 FPM700 650 600 550 500 450 400 350 300 250 200 150

400 371 343 320 286 263 235 208 182 153 120 87

CFM

alexandrahHighlight


Airflow on high speed with all filters clean and no ducting is about 400 CFM. The unit can be run with very dirty filters and virtually no flow without harming the unit. The operator’s decision to change filters should be based on filter cost vs. the unit’s filtering effectiveness. If airflow is 200 CFM vs. 400 CFM, the unit will filter particles from a space at half the rate. The operator must judge if that is acceptable.

If the operator determines the filters should be changed due to low airflow, it is most economical to change them in the following order:

Change the pad pre-filter (top) first. This is the least expensive filter. Recheck the airflow. If the airflow is acceptable, no other filters need to be changed.

Change the pleated fabric filter (middle) second. It is the second least expensive filter. Recheck the airflow.

If acceptable, the HEPA filter does not need changing.

If the airflow is still too low, the HEPA filter must be changed. To remove the HEPA filter, follow these steps:

�. Loosen the two 3/8” thumbscrews that secure the HEPA filter.

2. Push down on the filter hold-down bar and out on the back of the cabinet to disengage the two “ears” from the back of the cabinet. Rock the filter hold-down bar up towards the front of the cabinet.

3. Disengage the screw and spacer from the hole in the front of the cabinet and remove the filter hold-down bar.

4. Lift the old filter straight up and out of the cabinet. Place the new HEPA filter with the open side down, into the cabinet. Be sure the four bumpers on the base center it.
